That style of dress looks frumpy on me. I'm petite & wear a size 6, but that type of dress makes me look huge. There's no way I'd wear that.
I, like you, just wear pants, skirts, jeans, etc that are a little big on my waist. The new style of waist that is cut a little lower is fabulous. I also love the fact that so many clothes now have stretch in them. I even have stretch jeans. They're awesome! Even with the stretch, the waist has to be a little big or I can't stand it. The funny thing is that I've been this way my whole life. When I was a little girl, I used to pull my pants up as high as I could (arm pits if they'd go that far) because I can't stand anything remotely tight on my waist.
